Question

构建JSON，我不需要＆＃34;：new＆＃34;和＆＃34;：编辑/：id＆＃34;路线。所以我要求rails不要创建那些但是当我指定不应该可路由的路由时（使用Be_routable匹配器）......它不起作用。有什么建议吗？

routes.rb：

Rails.application.routes.draw do
  resources :todos, :except => [:edit, :new]
end

routes_spec.rb：

require 'spec_helper'


RSpec.describe "routes for Todos", :type => :routing do


  it "routes get /todos to the todos controller index action" do
    expect(:get => "/todos").
      to route_to(:controller => "todos", :action => "index")
  end


  it "routes post /todos to the todos controller create action" do
    expect(:post => "/todos").
      to route_to(:controller => "todos", :action => "create")
  end


  it "routes get /todos/:id to the todos controller show action" do
    expect(:get => "/todos/:id").
      to route_to(:controller => "todos", :action => "show", :id => ":id")
  end


  it "routes patch /todos/:id to the todos controller update action" do
    expect(:patch => "/todos/:id").
      to route_to(:controller => "todos", :action => "update", :id => ":id")
  end

  it "routes put /todos/:id to the todos controller update action" do
    expect(:put => "/todos/:id").
      to route_to(:controller => "todos", :action => "update", :id => ":id")
  end


  it "routes delete /todos/:id to the todos controller delete action" do
    expect(:delete => "/todos/:id").
      to route_to(:controller => "todos", :action => "destroy", :id => ":id")
  end


  it "does not route to /todos/new" do
    expect(:get => "/todos/new").not_to be_routable 
  end
end

最后一次阻止抛出此错误：

Failures:

1) routes for Todos does not route to /todos/new
   Failure/Error: expect(:get => "/todos/new").not_to be_routable
     expected {:get=>"/todos/new"} not to be routable, but it routes to {:controller=>"todos", :action=>"show", :id=>"new"}
   # ./spec/routing/routes_spec.rb:43:in `block (2 levels) in <top (required)>'

所有其他阻止都可以

todos_controller.rb：

class TodosController < ActionController::API


  rescue_from ActiveRecord::RecordNotFound, :with => :not_found


  def create
    @todo = Todo.new(todo_params)

    if @todo.save
      render json: @todo, status: :created, location: @todo
    else
      render json: @todo.errors, status: :unprocessable_entity
    end
  end


  def show
    @todo = Todo.find(params[:id])
    render json: @todo, status: :ok, location: @todo
  end


  def index
    @todos = Todo.all
    render json: @todos, status: :ok #, location: @todos DOESN'T WORK 'location:' OPTION
  end


  def  update
    @todo = Todo.find(params[:id])

    if @todo.update(todo_params)
      render json: @todo, status: :ok, location: @todo
    else
      render json: @todo.errors, status: :unprocessable_entity
    end
  end


  def destroy
    @todo = Todo.destroy(params[:id])
    render json: @todo, status: :no_content, location: @todo
  end


  private

    def todo_params
      params.require(:todo).permit(:title, :content)
    end

    def not_found(e)
      render :json => { :message => e.message }, :status => :not_found
    end
end

Answer 1

您收到错误的原因是您无法使用此测试。

原因是这条路线：

/待办事项/：ID

是路由到SHOW操作的路由。

所以当你浏览

时

/待办事项/新

'：id'的值将为'new'。

您可以通过在show方法中添加'puts params [：id]'来检查这一点，然后在浏览器转到'/ todos / new'中，您将在日志中看到它将显示'new'。

您应该添加路线约束。例如：

get   'todos/:id'   => 'todos#show', constraint: { id: /\d+/ }

我强烈建议您阅读和理解的更多信息here。：）

编辑：约束限制param：id，以便只允许整数。
